Ups,
I changed my OS from Vista32 to XP Prof. and now I do have this spur, too.
Direct after release of ptt or changing preamp settings it goes up about
20 - 30 dB above noise level and falls down within 3 seconds.
Changing IF to 0 Hz puts it direct on the red line. SR does eliminate it
totally.
I did not notice it unter Vista.

That is probably the DDS "0 IF noise".

Subject: [FlexEdge] Flex-1500 spur
Hi,
On my Flex-1500, I have a spur at about -3500 at all times. Changing the
preamp setting makes it stronger/weaker for a short amount of time when
switching from 0 to +30 to 0, then settles back down. Anyone else see this?
Seems most noticeable on quiet bands, at around -120. Doesn't appear to be
anything in the shack.
